摘要：
Cu2ZnSnS4 (CZTS), a quaternary chalcogenide-based compound semiconductor, has attracted much interest in applications on absorber layers of thin film solar cells, due to its direct band-gap, high optical absorption coefficient, and medium band gap matched solar spectrum. There remains huge gaps between the current reported the highest conversion efficiency and the theoretical power conversion efficiency, which drive scientists and researchers to improve the efficiencies through thin film synthesizing methods. Among various methods to synthesize CZTS thin films, electrodepositon is of particular interest due to low cost, environmental friendly, large area deposition and room temperature growth. After briefly introduces the structure of CZTS thin film solar cells, this paper reviews three electrodeposition approaches to obtain kesterite precursors including: (a) sequential electrodeposition of metallic stacked layers on Cu, Sn and Zn, (b) simultaneous electrodeposition of metallic Cu, Zn, and Sn, and (c) quaternary or chalcogenide electrodeposition, Cu-Zn-Sn-S(Se). Meanwhile, the preparation of CZTS thin film solar cell absorption layer by those three kinds of electrochemical techniques and the progress in the corresponding device performance have been also discussed, and the existing problems correspond to each method are pointed out. Finally, three kinds of electrodeposition methods are analyzed and compared, optimization method and the trend of future development are proposed. © 2016, Materials Review Magazine.
